2U 4-Node High-Density Server

The GIGABYTE H273-Z80-AAN1 is a 2U rackmount barebones system housing four independent compute nodes. Each node supports dual AMD EPYC 9004 Series processors in LGA 6096 sockets, delivering high core density for parallel workloads. The platform targets data centres and enterprises requiring maximum compute throughput per rack unit.

Suited for storage-heavy clusters

This server suits operators running storage-intensive applications such as distributed databases, object stores or content delivery nodes that benefit from local Gen4 NVMe, SATA and SAS drives. It is not for buyers who need GPU acceleration, single-thread frequency optimisation, or a single large memory domain across all nodes. Builds requiring proprietary form factors or front-serviceable cabling should look elsewhere.

Sustained load thermal balance

Under continuous multi-node load the rear-access layout directs airflow across both CPU sockets and the 24 DIMM slots per node, maintaining stable DDR5 throughput. The 24 hot-swap 2.5-inch bays keep drive temperatures consistent during extended write-heavy phases, while the dual ROM architecture supports firmware resilience during long maintenance windows.

Questions about this item

What CPU sockets must I populate for each node to function?

Each node requires two LGA 6096 sockets for AMD EPYC 9004 series processors, so eight sockets total across the 4-node chassis.

Can I keep my existing 1 GbE network cabling when adding this server?

Yes, the system provides eight 1 Gb/s LAN ports via Intel I350-AM2 controllers, compatible with standard Cat5e or Cat6 infrastructure.

How do I verify all drive bays are active after installation?

Insert drives into the 24 hot-swappable 2.5" bays; each bay supports Gen4 NVMe, SATA or SAS and will appear in the BIOS or OS once a drive is seated and the node powers on.
